Years ago, the Texas Medical Center established a biobridge to exchange technology and support with Denmark. Now, the two organizations are coming together to advance three health tech startups through a unique accelerator.

TMC and Denmark-based BioInnovation Institute announced today that three companies from BII will join a customized accelerator program that will guide them toward a United States go-to-market strategy. The program will be built off of the TMCi Health Tech Accelerator program.

“At TMC, we are elevating our ability to create curated go-to-market experiences for hand-selected companies that have a relationship with our partners at the BioInnovation Institute and that are seeking to prepare for of market expansion in the U.S.,” says Emily Reiser, associate director of TMC Innovation, in a news release. “We are excited about the opportunity to collaborate with BII and these founders.”

The three startups will head to Houston next week and incubate for six months, working with TMCi advisers and mentors on their individual challenges within commercialization and U.S. expansion. The three companies in the program are:

  • Aiomic, which is developing Aiomic360, an AI platform for postoperative complications. "With automated tracking and real-time risk assessment, Aiomic360 will function as a quality management tool for hospitals, a decision support tool for healthcare practitioners, and an individualized patient empowerment tool for surgical candidates," per the release.
  • Also tapping into AI, Orbit Health's solution, Neptune, is using motion data from smartwatches to track Parkinson’s motor state and treatment response passively. "Its continuous and objective insights enable regular treatment personalization that is needed throughout the course of the disease to optimize patient outcomes and improve quality of life," reads the release.
  • HEI Therapeutics is enabling at-home hypothyroidism management. "The innovative solution includes a patented finger stick blood test and digital patient empowerment tools and aims to significantly reduce the share of patients that is poorly regulated with medication," according to the release.

The TMC and the Ministry of Foreign Affairs of Denmark launched the Biobridge in 2019. BII is a nonprofit organization with a few resources — the Bio Studio, Venture Lab, and Venture House — that support life science startups with resources and even funding of up to €3 million per projects and €1.8 million per company.

“As we strengthen our offering to support visionary healthcare innovators to develop products and solutions to address clear unmet needs, our partnership with Texas Medical Center allows BII startups to gain exposure to US market and ready themselves for US market entry. We are thrilled about this collaboration with the Texas Medical Center which is one of the largest life science ecosystems in the world,” says Tony Cheng-fu Chang, principal at BioInnovation Institute. “Through the customized accelerator program, these three healthcare startups will acquire critical insight to create field-ready plans for bringing their products and solutions to the US market.”

AI-optimized health startup with HQ in Houston takes its tech to the next level with new partner

ending cancer

Optellum, a startup whose technology helps doctors detect and treat lung cancer, has teamed up with one of the world's health care giants to broaden the software's reach.

On August 18, Optellum — whose U.S. headquarters is at Houston's TMC Innovation Institute — unveiled its new collaboration with the Lung Care Initiative at Johnson & Johnson, which racked up global sales of $82.6 billion last year. Optellum's key contribution to the partnership is its AI-powered software that aids medical professionals in detecting and treating patients with lung cancer.

With Optellum's AI-powered lung cancer diagnostics now being included in J&J's Lung Cancer Initiative, medical teams soon will enjoy access to an array of complementary technologies designed to improve diagnosis and treatment of early stage cancer. The Lung Cancer Initiative, launched in 2018 by J&J and Boston University, aims to prevent, detect, and cure lung cancer.

Lung cancer ranks as the world's most common type of cancer and leading cause of cancer deaths. About 1.8 million people around the world die from lung cancer each year. The current five-year survival rate is just 20 percent, primarily due to most patients being diagnosed after the disease has reached an advanced stage.

Optellum's Virtual Nodule Clinic software received clearance from the U.S. Food and Drug Administration (FDA) in March. Hospitals in the U.S. are rolling out the technology, with Asia-Pacific and European hospitals on track to eventually adopt the software.

The Optellum platform identifies and tracks at-risk patients, and assigns a "lung cancer prediction" score to lung nodules — small lesions, frequently detected in chest CT scans, that may or may not be cancerous.

"Optellum's vision is to redefine the early intervention of lung cancer by enabling every patient to be diagnosed and treated at the earliest possible stage, when the chances of cure are highest," the United Kingdom-based company says in a news release.

The startup — a 2019 graduate of the Texas Medical Center's accelerator — hopes to apply the technology to other lung diseases, such as chronic obstructive pulmonary disease (COPD).

Optellum recently was named one of the 101 best medical device startups in the United Kingdom. In June, the startup was among 38 AI projects chosen by the UK Department of Health and Social Care to participate in a roughly $50 million health care initiative.

Václav Potěšil, founder and CEO of Optellum, says the Johnson & Johnson collaboration represents a "significant milestone" for his company.

The J&J partnership "brings us one step closer to Optellum's vision of redefining early lung cancer treatment by helping every clinician in every hospital to make the right decisions and provide their patients the best chance to fight back," Potěšil says.

Of the 35 people employed by Optellum, three are based in the U.S. and the rest in the United Kingdom. The company's team also includes several part-time consultants, most of whom are based in the U.S. By the end of this year, Optellum plans to expand its U.S. team with several full-time hires, including a senior executive located in Houston.

Beginning next year in Houston, Optellum expects its technology to be available for patients in clinical settings.

For Potěšil, Optellum's mission is personal. He lost an aunt to lung cancer within a year of her Stage 4 diagnosis.

"I've seen firsthand how very healthy people can be killed, and it's still the most common and deadliest cancer worldwide," Potěšil is quoted as saying by the Texas Medical Center. "We are really focused on enabling cancer patients to be diagnosed at the earliest possible stage and be cured. It's not just the modeled data on the computer. It's addressing the right clinical problems to add value to doctors."

Houston startup with life-saving innovation receives $2M grant

for the children

A $2 million federal grant will enable Houston-based PolyVascular to launch human trials of what it hails as the first polymer-based heart valve for children.

In conjunction with the grant, Dr. Will Clifton has joined the medical device company as chief operating officer. He will oversee the grant as principal investigator, and will manage the company's operations and R&D. Clifton is president and co-founder of Houston-based Enventure, a medical innovation incubator and education hub. He previously was senior director of medical affairs at Houston-based Procyrion, a clinical-stage medical device company.

PolyVascular's Phase II grant came from the Small Business Innovation Research (SBIR) program, which promotes technological projects.

The PolyVascular heart valve will help treat congenital heart disease affecting more than 1 million around the world. PolyVascular plans to launch clinical trials of the valve in children 5 and over within two years.

"Congenital heart disease remains the most common category of birth defect and a leading cause of childhood death in the developed world," reads a March 30 news release from PolyVascular, founded in 2014.

PolyVascular says the valve can be implanted without surgery, and can avoid the use of valve replacements from humans or animals. Those valve replacements are difficult to find and often don't last too long, leading to frequent follow-up surgeries.

"Our aim at PolyVascular is to transform the care of children with congenital heart disease by developing an entirely new generation of valves made of medical-grade polymer devoid of any biological tissue," Dr. Henri Justino, chief medical officer at PolyVascular, says in a release. "The valves in use so far for children have been made of biological tissue. Unfortunately, our immune systems target and destroy this biological tissue, sometimes rapidly, rendering the valve ineffective."

The SBIR grant isn't the only win for PolyVascular in recent years.

In 2019, the startup came away with several honors in the 2019 Texas A&M New Ventures Competition. It won the pitch competition (complete with a $5,000 cash award), and received the Biotex Investment Prize, Amerra Visualization Services Prize, and GOOSE Society Investment Prize.

Also in 2019, PolyVascular, a member of TMCx's 2017 medical device cohort, won in the medical device and health disparities and equity categories at the fifth annual Impact Pediatric Health pitch competition. Additionally, the Southwest National Pediatric Device Consortium granted the company up to $25,000.

Last year, MedTech Innovator, a nonprofit accelerator in the medical technology sector, announced PolyVascular was one of 50 companies chosen to participate in the organization's flagship four-month accelerator program.

"During these uncertain and challenging times, the need for health innovations — specifically those that promise to deliver long-term value to the health care system and patients — is more critical than ever," said Paul Grand, CEO of MedTech Innovator.

Another Houston startup, Vivante Health, also was picked for the MedTech Innovator program. Vivante is a digital health company that helps people address digestive health and wellness.

TMC cancer therapeutic accelerator names inaugural cohort

cancer innovation

The Texas Medical Center named 15 groundbreaking researchers and companies to its inaugural class of the Accelerator for Cancer Therapeutics on Thursday. All hail from the Lone Star State.

The ACT program is the only accelerator focused on cancer treatment at the earliest stages of commercialization, thanks to a $5 million grant from the Cancer Prevention and Research Institute of Texas awarded to the TMC in the fall of 2019.

The nine-month program kicked-off at the end of January and will be run by TMC Innovation, according to a release from the TMC. It aims to provide the class with resources to help their oncology biotech projects reach new milestones, including even commercialization.

The inaugural cohort is made up of companies and researchers exploring immunotherapy, cell therapy, targeted therapy, cancer pain, and drug platforms. The group is split about evenly between companies and academic researchers. The group of Texans includes:

  • Raptamer Discovery Group
  • IDA Therapeutics
  • Elbrus Therapeutics
  • Parthenon Therapeutics
  • Lokesh Battula
  • Aumeta
  • Autoimmunity Biologic Solutions
  • Max Mamonkin
  • Qing Yi
  • Astero Alta
  • TEZCAT Laboratories
  • Anil Sood
  • Coactigon
  • Xiadong Cheng
  • IonTx

At the end of the nine months, the class will present an integrated strategic plan and at least one grant submission. They will also have the opportunity to pitch investors and corporations.

The class will also gain support in grant writing, chemistry, and funding opportunities, as well as mentorship.

"As the past year has shown, the pace of scientific discovery can be blistering," says Tom Luby, director of TMC Innovation. "At the same time, successfully translating research into effective therapies available to patients requires a mix of business, technical and regulatory skills that may not typically be available to researchers.

"By linking the participants with mentors who can both advance their scientific work and support the technical needs, we expect this first class of ACT participants will make a meaningful difference for cancer patients in Texas and beyond."

TMCx, which is also run by TMC Innovation, recently announced seven health tech companies that were selected to its 2021 class of its health tech accelerator.

Broader in scope that the ACT accelerator, the TMCx startups focus on an array of subject matters from heart health to artificial intelligence to extremity rehabilitation.

These are the 7 newest health tech companies to join TMCx

new to hou

Last year, TMCx, the Texas Medical Center's health tech startup accelerator pivoted to digital programming.

The accelerator revamped its program to allow for an initial Bootcamp stage that would bring in a larger group of startups and then, after the boot camp, the program would move forward with a smaller group through the official acceleration process.

"We hosted 21 companies, representing six countries and 10 states, who each engaged with subject matter experts, clinical leaders, and corporate partners," writes Emily Reiser, senior manager of Innovation Community Engagement at TMC Innovation, in a blog post. "Over half of which ended Bootcamp in advanced discussions with hospitals and/or corporate partners."

Through the bootcamp, TMCx has accepted seven startups into the program. These companies are currently engaged with the TMC community and are receiving support, mentorship, and other opportunities.

Houston medtech startup clears FDA approval for new surgical tool

precision surgery

Houston-based Prana Surgical will soon bring a new electrosurgical tool to operating rooms around the country. The Prana System officially cleared U.S. Food and Drug Administration (FDA) approval earlier this month.

"Receiving FDA clearance for the Prana System represents a defining milestone for our company," Joanna Nathan, CEO and co-founder of Prana Surgical, said in a news release. "Surgeons today are increasingly focused on achieving precise outcomes while minimizing disruption to healthy tissue. The Prana System was designed to support that shift by integrating targeting and excision into a single, streamlined tool."

Prana Surgical began as Prana Thoracic in 2022. Back then, the company primarily focused on developing screening tools for lung cancer diagnosis. It raised $6 million in series A funding rounds in 2023 and 2024 before transitioning to broader surgical needs in 2025.

The Prana System is a minimally invasive, image-guided, single-use tissue extraction tool designed to retrieve samples without damaging healthy tissue. The tool is still designed with the respiratory system in mind, helping Prana in the fight against lung cancer and other thoracic diseases.

Reducing the impact of tissue extraction via electrosurgery and enhanced image scanning can significantly reduce complications. The Prana System combines localization and tissue-cutting capabilities in one, which keeps surgeons from having to swap out components during a procedure, making for a smoother process. It can core, cut and feel blood vessels on the way toward the intended target, giving surgeons greater control over tissue preservation.

"Electrosurgery is foundational to modern surgery, but there is still opportunity to improve how energy-based tools are applied in minimally invasive settings," Nathan added. "Our goal is to introduce a new class of image-guided surgical tools that enable more precise intervention across a range of procedures."

The company projects sales of $7.5 billion from the Prana System in the United States, estimating that 2.5 million surgical modules will be able to use the new tool. While starting out focused on biopsies, the company plans to evolve the system into other procedures, such as ablation, in the future. It is also planning for a controlled U.S. clinical rollout as it moves toward commercialization

Texas still ranks as No. 1 in U.S. for inbound moves, but growth dips

by the numbers

Texas continues to be the country’s No. 1 magnet for newcomers from other states, giving a boost to the state’s economy. However, Texas’ appeal weakened in 2024 compared with the previous year, due in large part to spiking home prices.

An analysis of U.S. Census Bureau data by self-storage platform StorageCafe shows Texas saw net interstate migration of 76,000 people in 2024. Texas’ net interstate migration dropped nearly 50 percent from 2023, according to the analysis. Net migration refers to the number of incoming residents minus the number of outgoing residents.

California remained the top source of newcomers for Texas, sending nearly 77,000 residents to the Lone Star State in 2024, the analysis says. Florida ranked second, followed by New York, Colorado and Illinois.

“These trends reveal Texas’ continued pull from both high-cost coastal markets and other large Sun Belt states, resulting in a mix of affordability-driven and job-driven relocation,” StorageCafe says.

Putting a damper on the influx of new residents: a roughly 124 percent surge in Texas home prices over the past decade, according to StorageCafe.

“While the state remains significantly more affordable than California, its top feeder state, the once-wide pricing gap has narrowed,” says StorageCafe. “For many movers, Texas is still a relative bargain, but no longer an undisputed one.”

Nonetheless, Texas keeps attracting young, highly educated people, which bodes well for the state’s long-term economic outlook, StorageCafe says. More than half of new arrivals to Texas in 2024 held at least a bachelor’s degree, and the age of newcomers averaged 32.

Where are most of these young, highly educated newcomers settling?

Lloyd Potter, former Texas state demographer, tells StorageCafe that population growth in Texas is happening most rapidly in suburban “ring counties” at the expense of slowing growth in urban cores. Ring counties are on the outskirts of major metro areas.

“Many people are moving from urban cores to suburban rings seeking lower costs, newer housing, better schools, and more space,” Potter says. “Typically, a move to a suburban county will be within commuting or hybrid‑commuting distance of major metro economies.”

Artemis II makes historic call to space station with help from Houston Mission Control

History in the making

Still aglow from their triumphant lunar flyby, the Artemis II astronauts made more history Tuesday, April 7: calling their friends aboard the International Space Station hundreds of thousands of miles away as they headed home from the moon.

It was the first moonship-to-spaceship radio linkup ever. NASA's Apollo crews had no off-the-planet company back in the 1960s and 1970s, the last time humanity set sail for deep space.

"We have been waiting for this like you can’t imagine,” Artemis II commander Reid Wiseman called out.

For Christina Koch on Artemis II and Jessica Meir aboard the space station, it marked a joyous space reunion despite being 230,000 miles (370,000 kilometers) apart. The two teamed up for the world's first all-female spacewalk in 2019 outside the orbiting lab.

Koch told her “astro-sister” that she'd hoped to meet up with her again in space “but I never thought it would be like this — it's amazing.”

“I'm so happy that we are back in space together,” Meir replied, “even if we are a few miles apart.”

Houston's Mission Control arranged the cosmic chitchat between the four lunar travelers and the space station's three NASA and one French residents.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

By late Tuesday afternoon, the Artemis II astronauts had beamed back more than 50 gigabytes' worth of pictures and other data from the previous day's lunar rendezvous, which set a new distance record for humanity. The highlight: an Earthset photo reminiscent of Apollo 8's Earthrise shot from 1968.

"While they are inspirational and, I think, allow all of us to really feel a little bit of what they were feeling, there's also a lot of science hidden inside of those images," said Mission Control's lead lunar scientist Kelsey Young. “The conversations and the science lessons learned are just beginning."

During a debriefing with Young, the astronauts recounted how they spotted a cascade of pinpricks of light on the lunar surface from impacting cosmic debris. The flashes lasted mere milliseconds and coincided by chance with Monday evening's total solar eclipse.

Young said it was too soon to know whether the crew witnessed an actual meteor shower or more random, run-of-the-mill micrometeoroid hits. Either way, there were “audible screams of delight” in the science operations center, she said.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

The first lunar explorers since Apollo 17 in 1972, Wiseman and his crew are aiming for a splashdown off the San Diego coast on Friday to wrap up the nearly 10-day test flight. The recovery ship USS John P. Murtha left port Tuesday for the target zone.

It sets the stage for next year's Artemis III, a lunar lander docking demo in orbit around Earth. Artemis IV will follow in 2028 with two astronauts attempting to land near the lunar south pole.

As for the Orion capsule’s pesky potty, Mission Control assured the astronauts that no maintenance was required Tuesday. The toilet has been on-and-off limits to the crew ever since last week’s launch, prompting them to rely on a backup bag-and-funnel system for urinating.

NASA Administrator Jared Isaacman told the crew following the lunar flyby Monday night: “We definitely have to fix some of the plumbing” ahead of the next Artemis mission. Engineers suspect a clogged filter in the overboard flushing system.

Aside from the toilet and other relatively minor matters, the mission has gone well, Isaacman noted at a news conference Tuesday, “but I'll breathe easier when we get through reentry and everybody's under chutes and in the water.”
